So far I am using this solidity code
pragma solidity 0.4.24;
contract Converter{
function Converter(){
}
function stringToBytes32(string memory source) returns (bytes32 result) {
bytes memory tempEmptyStringTest = bytes(source);
if (tempEmptyStringTest.length == 0) {
return 0x0;
}
assembly {
result := mload(add(source, 32))
}
}
}
Is there a website or online tool to easily convert strings to bytes32?
If you have MetaMask installed, then the following works in the browser console:
> web3.padRight(web3.fromAscii('hello'), 34)
"0x68656c6c6f0000000000000000000000"
Online GUI here for converting bytes32 to string and the other way: https://blockchangers.github.io/solidity-converter-online/
Another online GUI:
Convert from a bytes32/hex into a string/number or vice-versa.
You can use the bytes32 library from npm
https://npm.devtool.tech/bytes32
$ npm install bytes32
$ npx bytes32
0x0000000000000000000000000000000000000000000000000000000000000000
$ npx string
0x737472696e670000000000000000000000000000000000000000000000000000
I made an online utility for via versa conversion of String to Bytes32. It is client side also, so everything runs on the browser.
You can use Web3 tools created by Neptune Mutual which has String to Bytes32 Converter and vice versa.
Cindercloud also had an online converter, as well as some other useful tools for interacting with ethereum and other chains.
For historical reasons, MetaMask injected web3@0.20.7 is deprecated. It has known security issues. It is no longer maintained by the web3.js team.
